I. Course knowledge overview section

Server hardware components (understand) Server storage data principle (understand) Server hardware working principle (understand) Server hardware performance comparison (understand) Server operating system introduction

II. Knowledge Review Server Classification Server Hardware Composition

III. Server Hardware Details CPU

Number of ways: Number of CPUs in the server

Core: Server Parallel Task Capability Disk

Interface: determines reading efficiency

Sata (household equipment) →scsi→sas (server)

Type: Decide on reading efficiency

Speed: determines storage efficiency

Home: 5.4k 7.2k

Enterprise: 10k 15k memory

Buffer: buffer write

Cache: cache read power array card: logical consolidation of multiple hard drives into one

Increase single hard drive capacity

Improve data storage efficiency

Improve data security Remote management card: remote open host, remote installation system

IV. High concurrency of server storage data methods

Storage data: CPU receives and processes data → saves in memory → permanently saves to disk to relieve storage pressure

Read data: CPU receives and processes data → reads in memory → hot data in disk improves reading efficiency Low concurrent storage

Storage data: CPU receives and processes data → Permanently saves to disk

Read data: CPU receives and processes data → reads in memory → hot data in disk improves reading efficiency
